I have a reef octopus in sump skimmer. I can not remember which model of the reefoctopus it is but i do know its rated for 1000L and uses the psk pump.

The skimmer over skim and waste about 30 to 40L of water once or twice a week, it never used to do it and it started about a month ago.
I can't figure out why and want to know if it happened with someone else as well or does anyone know why is it doing it?

Lol, i cant even begin to tell you how many times my skimmers has overflown!!
I have come up with a plan to prevent that & it works like a bomb...
I drill an overflow into the side (or bottom if there is space) of the cup just under the "overflow" level & glue a 10mm perspex/plastic pipe into the cup to allow the skimmate to flow back into the sump...

You can also try setting the skimmer to skim less wet & then slowly increase (over a couple weeks) until you find the right level...

Thanks @Visser, you gave me an idee what to do thanks because mine came with an hole in the bottum. I gues the overflow doesn't matter to go back into the once or twice a week.
Now I have to keep my cup clean, haha

Some of the causes of skimmer overflowing is the use of filter floss/matting when replacing with new filter floss.
Another cause is a bacterial bloom when using bio pellets.
Addition of some type of additive..

I got myself a skimmate collection system which has an auto shutoff feature should the skimmate collector get full.

With insump skimmers its always best to buy a delay switch cos when u have a power failure your sump.level rises and when.electricity comes back the level in your insump skimmer will be too high causing an overflow. the delay time switches on the skimmer 5 mins after the power has returned allowing simp water level to stabalise before skimmer is switched on.

Another important thing is the addition of a float valve in your sump which will switch off skimmet if your sump water level rises in cases of a malfunctioning auto top off unit or broken return pump.
